The Record

STOCKTON - Two people were carjacked less than two miles away from each other in a little over 12 hours Monday night and Tuesday morning in Stockton, authorities said.

A woman was getting into her car in the 600 block of East 3rd Street about 9:30 p.m. Monday when she was confronted by a man holding a silver object in his hand, police said. The man stole her 1992 Mercedes-Benz sedan, which is silver with paint damage on the hood, before fleeing south, officers said.

The car thief was described as a black man about 20 years old standing 5 feet 7 inches tall with a thin build, blue jeans and a black hooded sweatshirt, authorities said.

At 10:48 a.m. Tuesday, about 1 1/2 miles away, a 41-year-old man was standing by his vehicle near East Main and South Sutter streets when he was approached by three men brandishing handguns, police said. The men searched the victim's coat and took his phone, wallet, cash and keys before fleeing on Sutter Street in the man's silver 2006 Buick Lucerne, license plate No. 5TAK724, officers said.

The thieves were described as black males wearing hoods. There was no further description, authorities said.

TRACY - A 47-year-old Whittier man was killed Tuesday when a 1,800-pound concrete block fell on him while he was cleaning the drum of a concrete transport truck, officials said.

The victim was working inside the tumbler on a mixer truck in the 10000 block of West Linne Road in Tracy shortly before 3:30 p.m. when he was struck by a large slab of falling concrete, said David Bramell, division chief with the Tracy Fire Department. The victim was pronounced dead at the scene, officials said.

The victim worked for Express Chipping Inc., a concrete chipping management company based in Artesia, Bramell said. The man was contracted to clean the cement mixing truck for A & A Concrete Supply in Tracy, Bramell said.

The victim's name was not released Tuesday night pending notification of family, officials said.

STOCKTON - Police are looking for two armed men who broke into a north Stockton home Monday night and demanded money from a woman and her friends, authorities said.

The robbery occurred about 8:30 p.m. in the 8100 block of Bernay Drive. The victims complied with the robbers' demands, and no one was injured, police said.

Both robbers wore black masks, officers said. One was described as an Asian man standing 5 feet 7 inches tall with a thin build, black clothing and a long gun, authorities said. The other was a black man with black clothing and a handgun, police said.

The workers were cleaning out an irrigation ditch with a bulldozer when the skull was found about 10:53 a.m. near North Staten Island and West Walnut Grove roads, authorities said. Deputies responded to the scene and recovered the skull, which is being submitted to the Department of Justice for further testing, officials said.
